winscp 5.7.6 disconnecting after upgrade from win 8 to win 8.1

The last working version was 5.7.4. this version stated software was causing a disconnect.
Upgraded to 5.7.6 and connected, then would disconnect.
Repeated aborting and reconnecting with same results:
would disconnect and either would not find the server (time out) or would connect and disconnect and not reconnect.
protocol: sftp
using: GUI/Commander

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.
